GB/T 19844 -2018 Leaf spring stiffness test: Load is applied through a V-shaped loading block. First, the spring is slowly loaded to the maximum test load and unloaded to zero load, and then the spring is slowly loaded to the maximum test load and unloaded. The load and corresponding deformation during the loading and unloading process are recorded, and the relationship between load and deformation is drawn. curve. |
